' ;App1ication filed November 12, 1913. Serial No. 800,546.

., .JZ z'v/rom it may concern.

Be it known that LInion Gsus-rox'r, a citizen of the Republic of France, residing in Paris, France, have invented certain new and useful Improvements in Cinematographs for Projection in Natural Colors by the Three-Colors Process, of which the following is a specification In my application for patent of the United States filed 5th February 1912, Serial No. (375627, I have described a device for regulating objectives permitting, when the latter have been displziied simultaneously until the central clear, of displacing individually, along their axes the extreme objectives by means of movable nuts until the images furnished by the three objectives are clear and equal in size.

T he present improvement relates to a modification of this device permitting of producing the advancing or retreating movement of each of the extreme objectives by the mere operation of a lateral knob.

The following description with the aid of the drawings shownby way of example will furnish an understanding of the object and the advantages of this modification.

' Figure 1 is a longitudinal section through the frame of the objectives 0, 0 Q at the level of the axis of one of the knobs.

Fig. 2 is a vertical section through the axes of two knobs.

In said drawings letter 5/ designates the out the (am C being an obstacle, this cam is removed oy iningag it into the recess a formed in the said lens frame, by exerting a tractive effort on the knob B. A helical spring 1* placed around the rod 25 and bearing with one end on the cam and with the other on a membei integral with the lens' frame support, enables the cam to return automatically to its recess 6 in the lensframe when this recess confronts the eani located in the recess a, as the lens-frame is slid in. i f

In order that the lens-frame may be turned over, a symmetrical recess e has been formedon the other side the lensframe.

\Yhat is claimed is 1. In a photographic apparatus, a lensframe, and adjusting means therefor, comprising a cam, said frame having a recess for engagement with said cam, and said cam being movable into and out of said recess to permit removal of said frame.

2. In a photographic apparatus, a sup port, a lens-frame removably mounted in said support, and adjusting means therefor, comprising a cam, said frame having a recess for engagement with said cam, and said cam being movable into and out of said recess to permit removal of said frame.

3. In a photographic apparatus, a lensframe, and adjusting means therefor, comprising a cam, said frame having a recess lens frames (Z the lens frame su orts ini' for en a ement with said cam, and said cam which the extreme lens-frames are longitudinally adjustable, and IV a support for the lens-frame-support in which'the lensframe supports (Z are mounted. The lensframe supports (Z are adj ustable in the sup-- port lV for the lens-frame supports around the pivot 20 by means of thumb screws o, and also are adjustable on the pivot to around an axis perpendicular to the plane of Fig. l, by means of the thumb-screws .9.

To each knobB, a. spindle t is secured, which is terminated by an eccentric cam C located in the recess e of the lens-frame carrying an objective. By turning a knob B a longitudinal movement of the corresponding lens frame 9 is produced, either forward or backward.-

To place each lens frame in its lens frame support [1 or to withdraw it therefrom with being movable into and out of said recess to permit removal of said frame, and a means for pressing said cam into engagement with said recess.

4t. Ina photographic apparatus, a sup port, a plurality of lens-frames, one of which is removably mounted in said support, and adjusting means for one of the lens-frames comprising a cam, said frame having a recess for engagement with said cam, and said cam being movable into and out of said recess to permit removal of said removable lens-frame.

5. In a photographic apparatus, a support, a plurality of lens-frames, a plurality of which are removably mounted in said support, and adjusting means for a plu rality of said lens-frames, each comprising a cam, said frames each having a cam recess,

and each of said cams being movable into and out of said recesses topermlt removal 'of said removable lens-frames.

6. In a photographic apparatus, a lens-' frame, a lens-frame-support, and a support for said lens-frame-support,.'said lens-framesupport being adjustable inits support ona vertical and a horizontal axis, and said lens-frame being axially adjustable in said .lens-frame-support, and means for adjusting said lens-frame, said means being carried by said lens frame-support.

7. In a photographic apparatus, a lensframe, a lens-frame-support, and a support for said lens-frame-support, said lens-framesupport being adjustable in its support on a vertical and a horizontal axis, and said lens-frame being axially adjustable in said lens-frame-support, and means for adjusting said lens-frame, said means being carried by said lens-frame-support, said adjusting means comprising a cam.

8. In a photographic apparatus, a lens frame, alens-frame-support, and a support for said lens-framesupport, said lens-framesupport being adjustable in its support on a vertical and a horizontal axis, andsaid lens-frame being axially adjustable in said lens-frame-support, and means for adjusting said lens-frame, said means being carried by said lens-frame-support, said fad justing means comprising a cam and said cam being 'disengageable from said lens- .frame for permitting removal of the latter. 9. Ina photographic apparatus, a plurality of lenses in close proximity to one an other, one of which is mounted in an inde pendently movable lens-frame, alens-frame frame being axially adjustable in said lensframe-support, and means for adjusting said lens-frame, said means being carried by said lens-frame-support.

11. In a photographic apparatus, a plurality of lenses'in close proximity to one another, a plurality'of lens-frames in which said lenses are mounted, a plurality of lensframe-supports, and a support for said lensframe-supports, said lens-frames being axially adjustable in said lens-frame-supports.

1 2. Ina photographic apparatus, a plurallty of lenses in close proximity to one another, a plurality of lens-frames in which said lenses are mounted, a plurality of lensframe-supports', and a support for said lensframe-supports, said lens-frames being axi-' ally adjustable in said lens-frame-supports,

and means for adjusting said lens-frames, said means being carried by said lens-framesupports.

13. In a photographic apparatus, a plu rality of lenses in close proxn'nity to one another, a plurality of lens-frames in which said lenses are mounted, a plurality of lensframe-supports, and a support for said lensframe-supports, said lens-frame-supports being adjustable on transverse axes therein, 0

said lens-frames being axially adjustable in said lens-frame-snpports, and means for adjusting said lens-frames, said means being carried by said lens-frame-supports, and being movable independently of said support 5 for said lens-frame-supports.

14:. In a cinematographic apparatus opera'ting upon the three-color principle, the

combination of three objective frames, two

of which are adjustable, and adjusting means comprising for each objective a cam, said adjustable frames having recesses for. engagement with said cams, said cams being movable into and out of said recesses to per- 'mit removal of the frames, and springs for pressing said cams into engagement with said recesses.

'In witness whereof, I have hereunto signed my name in the presence of two-subscribing witnesses.
